Yes, that's right!

Yes, that's right!

I was using Apache JENA to validate shapes with SHACL-SPARQL.
Now I want to make the same shapes, but using SHACL-JS.
It is easier for me to create JavaScript functions than SPARQL.

From the address indicated, I installed the shacl on my mac book.

As I understand it. SHACL Playground does not read JavaScript files?

To test, I copied example 6.1 from the SHACL JavaScript Extensions
website (https://www.w3.org/TR/shacl-js/).
Three files were created (file with JavaScript function; Data graph
and Shape Graph).

The file with the Javascript function I put in a folder under http://localhost/.

And I run the following command line:

sh shaclvalidate.sh -datafile SHACL-JS-W3C-DataGraph.ttl -shapesfile
SHACL-JS-W3C-ShapeGraph.ttl

Apparently, SHACL is running the validation, but in the end, the
report appears without errors.

However, there is an instance of the Data Graph with an error, which
is not reported.

I am not able to identify where the problem may be or if the
JavaScript function is actually being executed.
